TESTING AND OPERATING PROCEDURES
GENERAL FURNACE OPERATION
Aft er installation of the furnace is complete, it is ready for opera-
tion. Th
e Honeywell Limit Control, in conjunction with a wall
thermostat, operates the distribution blowers and the draft blow-
er on the front of the furnace. Th
e limit control can be adjusted
to your desired blower On/Off times. Th
e factory settings are
100/150/200 (USA) and 100/150/175 for Canadian Installations.
Th
e wall thermostat setting operates the ON time of the draft
blower. If the temperature is below the setting on the wall ther-
mostat, the draft blower will come on. (Recommended setting at
5 to 10 degrees higher than other heating thermostats.)
Th
e fi rst two set points on the limit control operates the distribu-
tion blower(s). When the furnace plenum reaches the second set
point on the limit control, the distribution blower(s) will come
on. If the temperature falls to the fi rst set point, the distribu-
tion blower(s) will shut-off . Th
e rocker switch on the top of the
junction box gives you the option to run one blower or two. If
the switch is ON, both blowers will come on when the plenum
reaches the set temperature.
When the furnace reaches the third set point on the limit control,
the draft blower will shut-off . Th
e draft blower will come back on
if the temperature falls below the setting on the wall thermostat.
TESTING
Check the draft blower by turning the room thermostat up high
enough so that the draft blower turns on. Th
en lower the ther-
mostat setting until you hear it shut off .
Use a sheet of newspaper to test your draft by placing it inside the
furnace and lighting it.
STARTING A WOOD FIRE
Using Forced Air Draft
With completion of the tests above, you are ready to light the
furnace. Follow the operating steps.
CAUTION: DO NOT USE CHEMICALS OR FLUIDS TO
START THE FIRE. Never use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fl uid, or similar liquids to start or
“freshen up” a fi re in the furnace. Keep all such liquids well away
from the furnace while it is in use.
Do not over fi re your furnace! You should burn small loads of
wood in your furnace until you have become familiar with its
operation while burning the type and quality of wood that you’ve
chosen.
Open spin draft cap on ash door.
Pull the slide baffl
e rod to the front position.
Open the fuel load door and light fi re using kindling and several
sheets of newspaper, then close the furnace door. Th
e furnace
door should remain closed for 5 to 10 minutes in order to estab-
lish the fi re. If the fi re has established, you are ready to load the
furnace.
CAUTION: To prevent fl ame and smoke spillage, the slide baffl
e
must be pulled out and the fuel door must be cracked for ten
seconds before being fully opened.
Load the furnace, close the load door and push the slide Baffl
e
rod to rear.
Close the spin draft cap on ash door, leaving it cracked about the
diameter of a dime.
Th
e forced air draft cycles on demand from the wall thermostat.
Setting the U.S. Stove thermostat four degrees higher than your
existing thermostat is recommended. In operation, the power
draft blower will run until the U.S. Stove thermostat temperature
setting is reached. Th
e draft regulator on the forced air draft is
preset at the factory and should require no adjustment.
TAMPER WARNING
Th
is wood heater has a manufacturer-set minimum low burn
rate that must not be altered. It is against federal regulations to
alter this setting or otherwise operate this wood heater in a man-
ner inconsistent with operating instructions in this manual.
STARTING A COAL FIRE
If you burn coal, a forced air draft is required
Shut off FAD when fuel door is open
Open smoke pipe damper all the way. Open all draft controls on
your 1602. Pull the slide baffl
e forward.
Place about 10-15 lb. of coal in on the shaker grates. It should
come up to about half of the fi rst fi rebrick level.
Place crumpled paper over the coal and crisscross a couple hand-
fuls of dry kindling wood 3/4” in thickness on top of paper.
Ignite the paper and close loading door. Wait about 30 minutes
until coal fi re is established before adding more coal. NOTE:
NEVER load coal over the level of fi rebrick.
Close by-pass damper and set all draft controls to your own
needs. It may take 3 to 4 coal fi res to determine how your local
BANKING THE FIRE
For extended operation, such as overnight, the fi re will need to
be banked. To do so heap coal up along the sides and back of the
fi rebox so that the fi re gradually burns it over a longer period of
time. Th
e intensity of the fi re will also be reduced without letting
it go out. Follow the same procedure as for refueling. If possible,
avoid shaking, as a heavier layer of ash will help reduce the inten-
sity of the fi re during this time. Aft er loading, let the fi re establish
itself for about 30 minutes. Th
en close your damper and auto-
matic control to the point where the house does not become too
cold. It is important that you begin banking early enough before
retiring or leaving that you can make necessary adjustments aft er
the fi re is well established. To revive a coal fi re that is almost out,
(1) open the ash door and stove pipe damper and close the spin
damper under the door to get a good draft through the grate. (2)
place a thin layer of dry coal over the entire top of the fi re. DO
NOT POKE OR SHAKE THE FIRE AT THIS TIME! (3) aft er the
fresh coal has become well ignited shake the grate (just a little),
refuel. DO NOT burn coke, charcoal, high volatile bituminous
coal, sub bituminous, lignite or cannel coal (sometimes called
channel coal or candle coal). NEVER burn wax or chemically
impregnated sawdust logs - their intended use is for fi replaces
only.NEVER fi ll the stove or furnace above the fi rebrick or cast
iron liner.
